Abstract: A method and apparatus for measuring a physical quantity, property or condition and for transmitting a code representing the measured physical quantity, property or condition. The method includes the steps of developing a first signal in response to a physical quantity, property or condition, sampling the first signal to produce an instantaneous first signal value, assigning a first code to the instantaneous first signal value, and transmitting the first code for reception by a receiver. The method and apparatus are explained in connection with a vehicle tire monitoring apparatus wherein plurality of tire units measure tire pressures and temperatures and transmit values representing pressure and temperature to a central receiver located in a cab portion of the vehicle.
